LOQM-SHUTTLE AND FILLING-CARRIER omens-on.

[retested Dec. 15, 1908.

Applicationfiled July 1a, 1908. Serial No. 443,862.

To all whom it may concern:

Be it known that I, WILLrAi/r PARK-EB STRAW, a citizen of the UnitedStates, and

resident of Manchester, county of Hillsboro,

State of New Hampshire, have invented an Improvement in Loom-Shuttlesand Filing Carriers Therefor, of which the following (16' scription, inconnection with the accompanying drawing, is a specification, likeletters on the drawing representing like parts. I

This invention relates more particularly to looms rovided with means toeffect automatica y ,a chanqe in the operation of the loombeione the illin the active shuttleis completely exhausted, such looms being usually I{termed feeler :loorns because, of the operation of a device whichintermittingly enters the shuttle and feels the filling therein.

The Chang-in the operation of the :loom may he stoppage, or it may heJan-automatic replenishment of the filling in the active shuttle,bothioperations bein well known all the or conceal it until apredetermined amount u of the'filling is woven .ofi. Thereupon the thatif the fi art. Various forms of provided with a longitudinal recess orslot over ,whaoh the filling 151 so wound as .to cover feeling device ispermitted to .enter the recess or slot, and the desired ohange in theoperation of the loom isefieoted automatically. It Will be ap arenttothose skilled in the art llin -carrieris not angularly positioned Withinthe shuttle so .as to bring the recess or slot" directly opposite thefeeler. the

latter will-hot operate properly when the determined filling exhaustionis reached.

in automatic filling-replenishing looms of the type illustrated inUnited States Patent No. 529,940, granted November 27, 1894, toNorthrop, the filling-carriers are transferred automatically from afeeder or hopper to the running shuttle, and there is at times atendency of the filling-carrier to turn during transfer. As a result,after it has been inserted in the shuttle the recessor slot in thebarrel will not be directly opposite the feeleropenin Y in the side wallof the shuttle,, .;and hence t e feeler when it passes through suchopening cannot operateproperly at the required time.

The present invention has for its "hbj'ect the production of meanswhereby a fillingcarrier of the ty e referred tois always properlypositioned in the shuttle, and the inven} g-carriers have been used nsuch teeler looms, among others one in which the harrel of thefilling-carrier as,

tion is shown arranged for use in connection with an automaticfilling-replenishing loom of the before mentioned Northrop? type; I vThe novel features of the invention miillho, fully described in thefollowing specification and particularly pointedout the claims annexedthereto. I

shuttle and a fillingecarnier embodying sine; form of theresentinyention, ;the filling-ear; rier being s own asin position to be trans--view of the portion of the shuttle illustrated- Fig. 1,, with the baseandadj scent portion of thefilling-carrier in position therein indicatedby dotted lines; Fig. 3 s s-a longitudinal sectional detail-on the line3-3, Fig. 2

.Fig. 4 is :a transverse sectionon "the lines- 1, Fig. -1, lookingtoward the lefit, showingiailso a portion of the-filling feeder orhopper.

The filling-carrier ,or bobbin co rises la base 1 provided with aseniesofiann ar projections or rings 2, loi wel'l-known structure, and.abarrel 3 which is shown in Fig. 1 es; vided with a longitudinal recess,preferah ya slot 4 extended directly through thehmrnel at a part thereofto properly cooperate with the feeler, not shown and which iswellllr-nown in the art. Herein the'basel is shown as Gil- Figure 1 is asideelev'ation.oiafpor tionlciia ferred while a part of the nearerwallof the shuttle is broken out; Fig. 2 is a top plan slabbed oil topresent two 0- posite and parallel flat faces 5, located on t e samesides of the filling-carrier as rare the o enings of the slot 4, thefaces being :loeate between the; series of rings and the outerendof thebase.

It wlllhe understood (that in practioezthe filling is so Wound as tocover the slot 4 until woven oli to a redetermined extent, to permit thefeeler evice to enter the slot, hence the importance-oiproperlypositioning thefilling carrier in the shuttle.

The shuttle in its main characteristics is of well known construction,.the body 6 having" an opening 7 for the rec'e tion of the filling:carrier, and at one end 0 such opening are" located usual springwjaws 8havin their inner faces grooved at 9 to receive t eringsZ and hold thesame'when the filling-carrier is transferred to the shuttle from thefeeder.

An incllned guide 10 is located between the:: basesof the jaws, todirect the filling-cards? longitudinally; at the time it is inserted inth shuttle so that the-grooved jaws 8 may properly cooperate with therings 2.

Referringyto Fig. 4 a ortion of the feeder is-shown, viz: t e innerplate whic ion int

' of the filling-carrier in the shuttle is effecte( sustains thebases ofthe filling-carriers, and

said plate 11' is shown provided with periphslightly during transfer theshuttle has'been provided with means to correct such angular movementand to insure the POSltlOIllIlg of the slot 4 directly op osite the-feeler-open-- ing 14 in the side wal of the shuttle, Figs. 1 and 4. Tothis end the shuttle is provided with two upright metallic guides 15,divergmg from a common stem or base 16, Fig. 3, secured between the jawbases in any suits able manner, as by a stud 17, the guides beinglocated within the jaws and in parallelism with each other at their freeends and at sucha distance apart that the faces 5 of the base of thefilling-carrier will snugly enter between them, see Fig. 2. When thebase 1 is so positioned between the guides'the latter positively retainit from any angular displacement and insure the proper ositioning of theslot 4 with relation to the ff; ing 1 of the shuttle. The upper edges ofthe guides are inclined and form cam surfaces 18, to cooperate with thefaces 5 and turn the filling-carrier on its axis into proper angularposition should it be turned in its passage from the filling-feeder tothe shuttle during transfer. That is, if the faces 5 are not prolperlypresented they will be engaged by t e inclined edges 18 of the guidesand the fillingcarrier will be turned on its axis,'by such engagemenhasthe rings 2 are brought into cooperative relation with the jaws 8.

It will be seen that the angular positionin and maintained by meansseparate from the holding jaws; the latter'holdingthe filling- I carrierin the shuttle and positioning it longitudinally but having no controlover its angular position. i

Having fully described my invention, what eler-open- I claim as new anddesire to secure by Letters Patent is z 1. The combination, with afilling-carrier having a longitudinally'slot'ted barrel and a baseprovided with opposite, parallel, flat faces on the same sides as theopenings of the slot of a shuttle having an o ening inits side wall,jaws to engage and he dthe filling-carrier, and means to ooop 'fsfiewith the opposite flat faces of the base ofsaidfilling-carrier andinsure its position in" the shuttle with the openings of the slot in thebarrel opposite the opening in the shuttle wallf v 2. Thecombination,witlr a shuttle having holding jaws, and OPPOSil'IGlYlOOZtlJGd p081- tioning members having parallel engaging portions, of afilling-carrier 'having-itsbase provided with opposite arallel faces andwith means to be engage and held by said jaws, the parallel engagingportions of the positioning members engaging the opposite facesvon thebase and cooperating therewith angularly position the same intheshuttle,.

the inclined edges of the guides assisting in turning thefilling-carrier, when necessary, to bring the flat faces into positionbetween the guides;

In testimony whereof, I have signed my name to this specification, inthe presence of two subscribing witnesses.
